i couldnt find a good answer for my question so im asking u guys.. im planing on building a motor in the near future and i am just doing a little research on the diffrents between the two..
so that my question is whats the diffrents between the two?

 

i think "I" beam is more for all motor, and "H" beam is for turbo

 

Yea I beams are lighter .so i would prolly agree with him.Sorry i didnt explain ----,I beams are lighter and can spin faster at high R's and the H beams are stronger and heavier meant for lower R's.Im not saying you cant use H beams for all motor but I would think I beams would be ideal for all motor.I use H beams in my turbo d

 

Lol...I-beam ..H-beam...
What about crower I-beams :P they're supposedly stronger then there econo H-beams and or much moe expensive

 

So for a boosted B series you should get the I beams Would tuner toys "I-beams" be good for 400whp and 9K RPM?

sorry for the semi threadjack, but I have had the same question as you for a while as well.

 

tuner toys said both his h beam and i beams were good to 500hp with the supplies fasteners and with upgraded like arp 2000 or something even higher
